Abstract

Ultra-high-performance concrete (UHPC), is an innovative material that may be used in tandem with prefabricated bridge elements and systems (PBES). The material is characterized by an extremely high compressive strength and a usable tensile strength that allows for more optimized structural elements. However, the prohibitively high cost of proprietary UHPC mixes has slowed the adoption of the material to be widely used throughout the state of Georgia. The Georgia Department of Transportation (GDOT) seeks to solve this issue by investigating the feasibility of using locally and more affordable cementitious materials in developing a non-proprietary UHPC. In response, researchers at the Georgia Institute of Technology have developed a non-proprietary mix that replaces expensive cementitious materials with more available and affordable constituents.
